Temperature MIN/MAX/AVG

[Tetnobic]

Hello,
How can I get MIN/MAX/AVG informations about temperature variable ?
I see in ScriptAPI about metrics, method : getSensorVariableMetricsDouble
it's the right way ?

When I try this on my sensor variable :
var list = mcApi.metric().getSensorVariableMetricsDouble(1,0,1479823903);
list is empty

Can you help me ?
Thanks

@Tetnobic You can get it on two ways,

Option 1:

Assign uidTag for your temperature variable, and use it on the script. In this method it will return single object. You will not get list.

var myImports = new JavaImporter(java.io, java.lang, java.util, java.text);

with(myImports) {
var sVar = mcApi.uidTag().getByUid("temp-outside").getResource(); // Get sensor variable object with UidTag api
var minMaxData = mcApi.metric().getSensorVariableMetricDouble(sVar, 0,1479833863195); //(sensor-variable-object, from-timestamp, to-timestamp)
}

on minMaxData object will be as follows,

"minMaxData": {
    "minimum": 0,
    "average": 73.51,
    "maximum": 115.4,
    "current": 34.9,
    "previous": 34.9,
    "variable": {....}
}

Option 2:

You can call list of metrics range with timestamp and bucket-duration. BucketDuration is nothing but interval between metric values.

var myImports = new JavaImporter(java.io, java.lang, java.util, java.text);

with(myImports) {
var sVar = mcApi.uidTag().getByUid("temp-outside").getResource(); // Get sensor variable object with UidTag api
var listOfData = mcApi.metric().getMetricData(sVar.id, "Sensor variable", 1479733863195, 1479833863195, "6h", true); //(sensor-variable-id, from-timestamp, to-timestamp, bucket-duration, boolean-get-generic), here the bucket duration is 6 hours
}

Output as follows,

  "listOfData": [
    {
      "start": 1479755463195,
      "end": 1479777063195,
      "empty": false,
      "min": 40.5,
      "max": 43.3,
      "avg": 42.672998137802615,
      "samples": 537
    },
    {
      "start": 1479777063195,
      "end": 1479798663195,
      "empty": false,
      "min": 37.7,
      "max": 42.6,
      "avg": 40.97185185185186,
      "samples": 540
    },
    {
      "start": 1479798663195,
      "end": 1479820263195,
      "empty": false,
      "min": 34.9,
      "max": 38.4,
      "avg": 37.71923076923077,
      "samples": 546
    },
    {
      "start": 1479820263195,
      "end": 1479841863195,
      "empty": false,
      "min": 34.9,
      "max": 35.6,
      "avg": 34.96143617021263,
      "samples": 376
    }
  ]

hope this example will help you.

Wonderful !!!
Option 1 works for me like a charm !
